I think both will have good seasons...I'd currently rank Jennings a bit higher but Yoenis has more upside...remember that he was a rookie last year...is getting used to living here...I'm assuming that he still uses an interpreter for some if not all communication...just met got his family in the US after a trying ordeal...

I think Desmond might outperform Yoenis (all things considered) this season but Yoenis is only getting started...though Yoenis is a year older he still has a lot of growth in him, while Jennings is entering his prime.

Go with Yoenis...plus you'll probably get more funny fantasy team name possibilities with Yo' Momma.
